Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint sealing material and a wall coating method using the joint sealing material.

[0002]

2. Description of the Related Art Conventionally, a method for finishing a wall of a building is a so-called wet method in which soil or the like is mixed with water and the wall portion of the building is coated with the so-called wet method, or a wall material or a wall panel manufactured in a factory. There is a so-called dry method in which a plurality of sheets are arranged and attached to the wall portion to finish the wall. In addition, the dry method has been widely adopted recently because of its easy on-site construction and short construction period.

Many wall panels and wall panels used in this dry system have been invented in the past.
When a plurality of the wall materials or wall panels are arranged and attached to the wall portion, a gap called a joint is formed between the wall material or wall panel and the adjacent wall material or wall panel. If the gap between this wall material or wall panel and the adjacent wall material or wall panel is left as it is, not only will the appearance be poor, but rainwater will also intrude through this gap and the room will get wet, or this intrusion will occur. The soaked rainwater enters the wall and freezes, causing so-called frost damage that widens or damages the gap.

Therefore, in the conventional dry method, it is difficult to close the joint between the wall material or wall panel and the adjacent wall material or wall panel. To block this joint,
Conventionally, there is a method of inserting a rubber gasket into the joint and a method of filling the joint with a sealing material and coating from above, but the method of inserting the sealing material into the joint and coating from above has a conspicuous joint. It is preferable because it does not exist.

However, if the sealing material is inserted into the joint between this wall material or wall panel and the adjacent wall material or wall panel and the coating is applied from above, the wall material or wall panel will be affected by the temperature difference between summer and winter. Expands and contracts, and the joint width changes, causing cracks in the sealing material and coating film that close the joints, which is not only ugly but also causes the problem that rainwater enters through these cracks and causes frost damage. is there.

As a method for finishing this joint, Japanese Patent Publication No.
As described in Japanese Patent Publication No. -13702, there is known a method in which an adhesive tape having a release treatment applied on the back surface and a gauze cloth tape are applied, and an elastic paint and a normal paint are applied on the adhesive tape. In this method, since the back surface of the pressure-sensitive adhesive tape is subjected to release treatment, the back surface of the pressure-sensitive adhesive tape and the elastic coating material are not completely adhered. Therefore, even if the wall material or the wall panel expands or contracts due to the temperature difference in the summer and winter, the elastic paint or the gauze cloth in the non-adhered portion expands or contracts, and a crack or the like does not occur in the coating film on the joint, which is a preferable method. .

[0007]

However, the above method requires a number of steps such as sticking an adhesive tape or a cotton syrup tape and coating two layers from the above, which is inconvenient and inconvenient in the work site. Since the advantages of the dry method that the construction is easy and the construction period is short are lost, it is strongly requested by the contractor to construct the joint easily and quickly.

Further, in the above method, since four layers such as an adhesive tape, a gauze tape, an elastic paint, and an ordinary paint are provided on the joints, this portion becomes thicker and the back surface of the adhesive tape is subjected to a releasing treatment. Therefore, there is a problem in that the elastic paint provided thereon is repelled and becomes non-uniform, resulting in unevenness on the coated surface, which is ugly. Therefore, an object of the present invention is to provide a joint sealing material suitable for easily and beautifully finishing a joint between a wall material or a wall panel and an adjacent wall material or wall panel, and a wall using the joint sealing material. It is to provide a painting method.

[0009]

The present invention has been made to solve the above problems and achieve the above objects.
The joint sealing material of the present invention is one in which an elastic paint layer is provided on the surface of a flexible and long base material having elasticity, and an adhesive layer is provided on the back surface. Further, in the wall coating method of the present invention, a plurality of wall materials or wall panels are mounted side by side on a wall portion of a building, and the joint seal is provided at a joint between the wall material or wall panel and an adjacent wall material or wall panel. The material is placed along the joint in the longitudinal direction of the long base material, the width direction is passed from the wall material or wall panel to the adjacent wall material or wall panel, and the adhesive layer on the back surface is brought into contact with the wall material or wall panel. After sticking, the wall material or wall panel and the joint sealing material are painted.

The elastic flexible long base material used in the joint sealing material of the present invention is a flexible and elastic material such as rubber formed into a long body such as tape.
It is preferable to use rubber such as natural rubber or synthetic rubber, or soft synthetic resin such as soft urethane resin, soft vinyl chloride resin, or acrylic acid resin, which is molded into a long body such as a tape. In particular, a tape formed of a soft urethane resin is preferable. The elastic paint used in the joint sealing material of the present invention is one in which the coating film after coating has elasticity, and urethane-based paints and acrylic-based paints are suitable, and particularly,
Acrylic paints are preferred.

A typical method for providing a pressure-sensitive adhesive layer on the back surface of the base material of the present invention is to apply a pressure-sensitive adhesive dissolved in a solvent on the back surface of the joint sealing material, and then dry it or directly apply the pressure-sensitive adhesive to the joint sealing material. It is provided on the back side. As the pressure-sensitive adhesive used at this time, all the conventionally known pressure-sensitive adhesives can be used, but an acrylic pressure-sensitive adhesive is preferable because it has good weather resistance and high adhesive strength.

[0012]

In the present invention, first, a plurality of wall materials or wall panels are mounted side by side on the wall portion of the building. Next, a joint sealing material according to claim 1, that is, a joint between the wall material or wall panel and an adjacent wall material or wall panel, that is, an elastic paint layer is provided on the surface of a flexible long base material having elasticity. The joint sealing material provided with an adhesive layer on the back surface is arranged along the joint in the longitudinal direction of the long base material, and the width direction is passed from the wall material or wall panel to the adjacent wall material or wall panel, Attach the adhesive layer on the back to the wall material or wall panel in contact with it. Finally, paint is applied over the plurality of wall materials or wall panels and the joint sealing material.

Then, the joint sealing material is placed over the joint between the wall material or wall panel and the adjacent wall material or wall panel, and is attached by adhesion, and the coating is applied thereon. Therefore, even if the wall material or wall panel expands or contracts due to the temperature difference between summer and winter and the width of the joint changes, the adhesive layer, the long base material having elasticity, and the elastic coating change the joint width. And does not affect the paint applied on top of this, and does not crack on this painted surface. Further, in this coating method, since it is sufficient to apply a joint sealant on the joint and apply the coating on it, the construction is extremely simple. In addition, since the joint sealing material can be manufactured at the factory, it is possible to obtain uniform quality,
If you apply a coating on this, it will be beautiful without any unevenness on the coated surface.
